A former Porirua man was just minutes from his Sydney home when he died in a car crash which also involved two trucks.

Daniel Melemele Faiva, 33, was killed in the crash in Colyton, west Sydney, about two kilometres from his home, last Wednesday.

He was on his way home to wife Jenelyn and their two young sons, Tyler and Kingston.

Police are investigating and will prepare a report for the coroner. No charges have been laid.

Daniel Faiva grew up in Titahi Bay and moved to Sydney in 2004, expecting to stay a couple of years. Two years later he met Jenelyn and proposed six months after their first date.

Jenelyn Faiva, who described herself as "always smitten", said from Sydney: "He was the most generous, humble, humorous, genuine and loveable person. A genuine all-round nice guy with a great sense of humour, and he just exuded positive energy.

"He would go out of his way to say hi to you, no matter what, and he made everyone feel welcome and at ease with his presence."

Daniel Faiva was a team manager for National Australia Bank, and his wife said his co-workers were devastated by his death.

A family friend on Facebook described him as "just a genuine, humble, kind man". "Mele's humour was straight out of a comedy script - always a good laugh whenever he was nearby."
